Four Days In August (FDIA) Just Keeps Getting Better!

FDIA 2026 is officially on the runway, and this is the second weekly update for Four Days in August: Hams Helping Hams. In this series, I’ll be sharing the latest event plans, schedule updates, activities, presenters, locations, and anything else you’ll want to know before we all roll into Huntsville for four days of playing radio, learning things, sharing what works, and supporting each other.

👉 Official "Program": https://temporarilyoffline.com/blogs/tos-blog/2026-four-days-in-august
👉 Monte Sano State Park: https://www.alapark.com/parks/monte-sano-state-park
👉 Huntsville Hamfest: https://hamfest.org/
👉 Signals Museum: https://www.signals-museum.org/
👉 The Elmer Brand Choke Kits: https://theelmerbrand.com/
👉 Performance Z Arrays: https://www.performancezarrays.com/

❤️ Get My Free Newsletter: https://temporarilyoffline.com/pages/newsletter-signup

This isn’t meant to be another sit-in-a-chair-and-watch-PowerPoint event. FDIA is built around the idea of hams helping hams in the field, on the bench, under a pop-up canopy, around antennas, radios, projects, and practical skills. Keep an eye on these weekly updates as the event takes shape, and start making your August plans now.

Grab a Coffee – I Need to Download

Grab a Coffee - I Need to Download

There’s LOTS to cover today:

• Project X (without giving too much away…)
• Building a true Multi-2 contest station
• A possible DX Commander remote station network
• Remote operating from anywhere
• KiwiSDRs and low-noise receive sites
• Upcoming antenna experiments
• Future video ideas
• What life behind the scenes at DX Commander actually looks like

I’d genuinely like your thoughts on one idea in particular… Would you be interested in being part of a shared remote station network? Imagine having access to a serious station in a quiet RF location without having to build it yourself.

Let me know in the comments. As always, I read all of them.

Band-Pass Filters – Do You Actually Need One?

Post author By admin
Post date July 18, 2026

Band-Pass Filters - Do You Actually Need One?

Band-pass filters are common in serious contest stations and multi-operator setups, but what do they actually do… and do you really need one?

In this video I explain the difference between a notch filter and a band-pass filter, how modern transceivers already include front-end band-pass filtering, and why adding an external band-pass filter can further reduce unwanted signals and harmonics.

Using my own station as an example, I show why I use an external band-pass filter when running multiple stations at the same time, and discuss whether there are any benefits for a single-operator station.

We’ll also cover:

What a band-pass filter actually does
How it differs from a notch filter
Why flagship radios have sophisticated front-end filtering
Multi-station interference and harmonic suppression
Whether an external band-pass filter is worth the investment

I’d be interested to hear your thoughts. If you use an external band-pass filter, or you’ve found it made a noticeable difference in your station, let us know in the comments.

73,
